Ground Protect.
Ground Timed1 O/C
Relay
Value
- - -
RANGE: NONE; ANY COMBINATION OF TRIP, AUX1 OR AUX2.
Select the outputs to be activated by the ground timed 1 overcurrent protection
(ANSI 51.1 N/G).
Ground Protect.
Ground Timed1 O/C
Pickup
Value
12 %CT
RANGE: 1
300
STEPS: 1
Enter the ground overcurrent pickup level. This level determines the current level
at which the relay will start counting the circuit breaker/disconnector trip time
according to the protection curve selected in the following line:
GROUND O/C

Delay
Value
1.00 s
RANGE: 0.01

STEPS: 0.01, 0.1, 1
Enter the ground timed 1 overcurrent delay. The related output will activate if the
current rating is superior to “GROUND TIMED O/C PICKUP” for a longer time than
the set one.
